________ is not an example of artificial vegetate propagation.

Options

A. Cutting
B. Grafting
C. Layering
D. Runner

Answer

### Step-by-Step Solution:

1. **Understand the Types of Vegetative Propagation**:
- There are two main types of vegetative propagation: artificial and natural.
- Artificial vegetative propagation involves human intervention to help plants reproduce, while natural vegetative propagation occurs without human assistance.

2. **Identify the Options Given**:
- The options provided are:
1. Cutting
2. Grafting
3. Layering
4. Runner

3. **Analyze Each Option**:
- **Cutting**: This is a method where a part of the plant (like a stem or leaf) is cut and planted to grow a new plant. This is an artificial method.
- **Grafting**: This involves joining parts from two plants so they grow as one. This is also an artificial method.
- **Layering**: This technique involves bending a stem to the ground and covering it with soil to encourage roots to form. This is considered artificial propagation.
- **Runner**: This is a natural method where horizontal stems grow along the ground, producing new plants at nodes. An example is grass.

4. **Determine the Correct Answer**:
- Since cutting, grafting, and layering are all artificial methods of vegetative propagation, and runners are a natural method, the correct answer to the question is **runner**.

### Final Answer:
**Runner** is not an example of artificial vegetative propagation.
